Decurler apparatus for reducing cross curl in sheets

摘要

A decurler for reducing cross curl in sheets includes at least one grooved elastomer transport belt and a ribbed pinch shaft. The ribs of the decurler shaft extend into the grooves in the belt to provide one-sided corrugations to a passing sheet and provide distributed localized bending of the copy sheet in the area of the belt grooves. Distributed local bending in the cross direction, as well as, in the wrap in the process direction around the ribbed decurler shaft provide cross curl reduction in the process direction.
